MARTINEZ — A Dublin-based California Highway Patrol officer is suspected of secretly sending nude photos of a DUI suspect from her cellphone to his own phone, according to court documents obtained Wednesday.

A Contra Costa District Attorney investigator has recommended felony computer theft charges against CHP officer Sean Harrington, 35, of Martinez, according to search warrant records obtained by this newspaper. The five-year CHP veteran has been assigned to desk duties during the probe, a CHP spokeswoman said.

“We’ve been investigating this for quite some time, the investigation is coming to a conclusion and we expect to make a charging decision this week,” deputy district attorney Barry Grove said Wednesday. He declined to comment on whether other officers have been implicated in the investigation, although an attorney representing the woman believes other officers and victims will surface.
